A Jersey City LEGO “master” faces up to seven years in prison when he is sentenced today, having pleaded guilty to molesting children while leading a LEGOs afterschool activity in more than one Hudson County school, officials said.

Eric Sophie, 42, of Newport Parkway, pleaded guilty to two counts of sexual assault and one count of endangering a minor and will be sentenced at 1:30 p.m. by Hudson County Superior Court Judge Lisa Rose in the Hudson County Administration Building in Jersey City.

Sophie was initially arrested in November 2010 and charged with molesting two 5-year-old girls and an 8-year-old girl, officials said. Soon after that he was charged in a fourth incident, officials said. Hudson County Assistant Prosecutor Jane Weiner said Sophie has been in the Hudson County jail in Kearny since his arrest.

Sophie, who called himself “Legomaster” on his MySpace.com page, ran an after-school program at Ethical Community Charter School on Broadway in Jersey City.

Hudson County Assistant Prosecutor John Mulkeen said at the time of Sophie’s arrest that the charges stemmed from incidents in Jersey City and Hoboken.

Sophie’s intricate, complex and often large LEGO creations have been exhibited in Liberty State Park, on the Jersey City Artists Studio Tour, on the “Good Day, New York” television program and numerous other venues.
